Professional career
Jáuregui was born on 5 September 1973 (in Guadalajara, Jalisco) and turned pro in 1988 at the age of 14. After 15 years, in 2003, he captured the vacant IBF Lightweight Title with a TKO over Leavander Johnson. He lost the title in his first defense to Julio Díaz in 2004.

Death
It was reported on December 11, 2013, that Jauregui had suffered a stroke in Jalisco, Mexico, and been declared braindead. He died later that day, after a short period in a coma. Some speculated that his Brain injury could have been caused by a hard sparring session with Canelo Alvarez a day prior.
